Farming, yes must have pretty good future, but it is also hard work.
One acre is the land one man with a horse can plow/tender in one day; so it is limited how many acres you can handle.
Another problem is that an average horse only puts out half a horsepower of work instead of the full one, so you get chipped when you buy one, on top of that it eats twice as much as a cow.
Solution; get someone to do the hard work for you and buy Agrium stocks; they are my only non-gold holdings and doing well.
